TEAMtalk looks at some of Sir Alex Ferguson's outbursts at officials after the FA asked him to explain his comments about linesman Simon Beck.
Manchester United boss Ferguson has been contacted by the Football Association to explain comments he made to the media about Beck following Sunday's 1-1 draw with Tottenham at White Hart Lane, where the hosts grabbed a late equaliser after Wayne Rooney had been denied a penalty.
"The stand-side linesman never gave us a thing all day," Ferguson told Sky Sports. "For me, it was a poor performance by him. Why he never saw the penalty kick on Wayne Rooney and some of the other decisions...
"We remember him well from the Chelsea game (in 2010) when (Didier) Drogba was three yards offside and he gave him onside.
"I think he had a shocking game. I'm disappointed in his performance, I really am. I think he had a bad game."
Here, TEAMtalk looks back at some of his other outbursts at officials.
Hit with a two-match touchline ban and a £10,000 fine for a sustained four-letter outburst at fourth official Jeff Winter during a game at Newcastle. Ferguson had been angered by some decisions made by referee Uriah Rennie and kicked a ball in frustration before remonstrating with Winter, for which he was sent to the stands.
Accepts a two-match touchline ban and £5,000 fine after admitting a charge of "using abusive and/or insulting words" towards referee Mark Clattenburg. Incensed by Clattenburg's failure to clamp down on Bolton's "over-aggressive tactics" during a defeat at the Reebok Stadium, Ferguson had ranted at the official at half-time and was sent to the stands for the second period.
Stung with another two-match touchline ban and £10,000 fine for shouting angrily at referee Mike Dean after a game against Hull. Ferguson fumed after Dean failed to send off Hull's Andy Turner for a foul on Michael Carrick and after the Tigers were awarded an innocuous penalty.
Receives a four-match touchline ban, two of which were suspended, for questioning the fitness of referee Alan Wiley after a draw against Sunderland. "The pace of the game demanded a referee who was fit. He was not fit," said Ferguson, who later issued an apology.
Punished with a five-match touchline ban and £30,000 fine for questioning the integrity of referee Martin Atkinson after a match at Chelsea.
"You want a fair referee, or a strong referee anyway - and we didn't get that," he said. The remarks were deemed worthy of a three-game suspension and that triggered the suspended ban hanging over from the Wiley affair.
Escapes punishment after confronting Mike Dean, assistant referee Jake Collin and fourth official Neil Swarbrick to protest after a Newcastle goal was allowed to stand at Old Trafford on Boxing Day despite initially being ruled out for offside. Newcastle boss Alan Pardew suggested Ferguson should have been sent to the stands for his outburst but the Scot hit back at his counterpart, saying he was the manager of a "wee club in the North-East".
